SD! is not yet compatible with Leopard. The current build was compatible with Leopard from back in February, but things have changed since then. We don't have the final bits, so we cannot test. A Leopard compatible version will be released when we have that final build and can complete testing...

I'm sure Leopard will be a good release. But... it might be a good idea -- as always -- to wait a little while to make a major change.
